在启动 sdc 后在 emr 中安装流集时面临以下问题,我们给出以下命令

ssh -N -p 22 hadoop@ec2-34-207-150-21.compute-1.amazonaws.com -i /home/hadoop/sterling-emr-keypair.pem -L 18630:localhost:18630

给出的错误是:

bind: Address already in use
channel_setup_fwd_listener: cannot listen to port: 18630
Could not request local forwarding.
^CKilled by signal 2.

由于这个错误,我无法访问本地主机上的 stremsets UI
